  %SPEAKER NOTES: See comments below
%
    \textbf{The Paradox:} Human operators are both essential for flexibility and the primary source of failure

    \textbf{Why We Need Humans:}
    Strategic decision-making, procedure interpretation, handling novel situations, adaptive judgment, legal authority (10 CFR 55)

    \textbf{Why Humans Fail:}
    Working memory: 7±2 items, response time: seconds vs milliseconds, cognitive biases (confirmation, anchoring), stress degrades performance 10-50x, error rates: 0.001 → 1.0 under accident conditions

    \textbf{Current Division:}
    Automated = Emergency protection (trip systems, ECCS) --- terminal operations;
    Manual = Strategic operations (startup, mode transitions, power changes) --- routine operations

    \textbf{Goal:} Reliability of automation with sophistication of human decision-making
